If you are a Windows 11 or Windows 10 user that made the June 28 and June 26 updates respectively, then you might have encountered an issue while trying to open XML Paper Specification (XPS) documents in some non-English languages using XPS Viewer.
According to Microsoft:
Microsoft has further indicated that they are currently investigating the matter, however, they have not provided a workaround for the issue. They have indicated that they are looking for a way to resolve it and will probably fix the issue in a subsequent release.
Though Windows 10 users will not be adversely affected by this issue as "XPS Viewer is no longer installed by default as of Windows 10, version 1803". Although you can still install it manually. In other related news, last month, Windows 10 KB5015807 update was causing issues with printing, the same also applies to the KB5014666 released on June 28.
